Hi, all!

The ghostly radio station that no one claims to run

"MDZhB" has been broadcasting since 1982. No one knows why.

In the middle of a Russian swampland, not far from the city of St
Petersburg, is a rectangular iron gate. Beyond its rusted bars is a
collection of radio towers, abandoned buildings and power lines bordered
by a dry-stone wall. This sinister location is the focus of a mystery
which stretches back to the height of the Cold War.

It is thought to be the headquarters of a radio station, "MDZhB", that
no-one has ever claimed to run. Twenty-four hours a day, seven days a
week, for the last three-and-a-half decades, it's been broadcasting a
dull, monotonous tone. Every few seconds it's joined by a second sound,
like some ghostly ship sounding its foghorn. Then the drone continues.

Once or twice a week, a man or woman will read out some words in
Russian, such as "dinghy" or "farming specialist". And that's it.
Anyone, anywhere in the world can listen in, simply by tuning a radio to
the frequency 4625 kHz.

It's so enigmatic, it's as if it was designed with conspiracy theorists
in mind. Today the station has an online following numbering in the tens
of thousands, who know it affectionately as "the Buzzer". It joins two
similar mystery stations, "the Pip" and the "Squeaky Wheel". As their
fans readily admit themselves, they have absolutely no idea what they
are listening to.

In fact, no-one does. "There's absolutely no information in the signal,"
says David Stupples, an expert in signals intelligence from City
University, London.

What's going on?

The frequency is thought to belong to the Russian military, though
they've never actually admitted this. It first began broadcasting at the
close of the Cold War, when communism was in decline. Today it's
transmitted from two locations - the St Petersburg site and a location
near Moscow. Bizarrely, after the collapse of the Soviet Union, rather
than shutting down, the station's activity sharply increased.
There's no shortage of theories to explain what the Buzzer might be for
- ranging from keeping in touch with submarines to communing with
aliens. One such idea is that it's acting as a "Dead Hand" signal; in
the event Russia is hit by a nuclear attack, the drone will stop and
automatically trigger a retaliation. No questions asked, just total
nuclear obliteration on both sides.

This may not be as wacky as it sounds. The system was originally
pioneered in the Soviet era, where it took the form of a computer system
which scanned the airwaves for signs of life or nuclear fallout.
Alarmingly, many experts believe it may still be in use. As Russian
president Vladimir Putin pointed out himself earlier this year, "nobody
would survive" a nuclear war between Russia and the United States. Could
the Buzzer be warding one off?

As it happens, there are clues in the signal itself. Like all
international radio, the Buzzer operates at a relatively low frequency
known as "shortwave". This means that - compared to local radio, mobile
phone and television signals - fewer waves pass through a single point
every second. It also means they can travel a lot further.

While you'd be hard pressed to listen to a local station such as BBC
Radio London in a neighbouring county, shortwave stations like the BBC
World Service are aimed at audiences from Senegal to Singapore. Both
stations are broadcast from the same building.

hierarchy it would automatically trigger a retaliation (Credit: Public

It's all thanks to "skywaves". Higher frequency radio signals can only
travel in a straight line, eventually becoming lost as they bump into
obstacles or reach the horizon. But shortwave frequencies have an extra
trick - they can bounce off charged particles in the upper atmosphere,
allowing them to zig-zag between the earth and the sky and travel
thousands, rather than tens, of miles.

Which brings us back to the Dead Hand theory. As you might expect,
shortwave signals have proved extremely popular. Today they're used by
ships, aircraft and the military to send messages across continents,
oceans and mountain ranges. But there's a catch.

The lofty layer isn't so much a flat mirror, but a wave, which undulates
like the surface of the ocean. During the day it moves steadily higher,
while at night, it creeps down towards the Earth. If you want to
absolutely guarantee that your station can be heard on the other side of
the planet - and if you're using it as a cue for nuclear war, you
probably do - it's important to change the frequency depending on the
time of day, to catch up. The BBC World Service already does this. The
Buzzer doesn't.
Another idea is that the radio station exists to "sound" out how far
away the layer of charged particles is. "To get good results from the
radar systems the Russians use to spot missiles, you need to know this,"
says Stupples. The longer the signal takes to get up into the sky and
down again, the higher it must be.

Alas, that can't be it either. To analyse the layer's altitude the
signal would usually have a certain sound, like a car alarm going off -
the result of varying the waves to get them just right. "They sound
nothing like the Buzzer," says Stupples.
Intriguingly, there is a station with some striking similarities. The
"Lincolnshire Poacher" ran from the mid-1970s to 2008. Just like the
Buzzer, it could be heard on the other side of the planet. Just like the
Buzzer, it emanated from an undisclosed location, thought to be
somewhere in Cyprus. And just like the Buzzer, its transmissions were
just plain creepy.
At the beginning of every hour, the station would play the first two
bars of an English folk tune, the Lincolnshire Poacher.

"Oh 'tis my delight on a shining night
In the season of the year
When I was bound apprentice in famous Lincolnshire
'Twas well I served my master for nigh on seven years..."

After repeating this12 times, it would move on to messages read by the
disembodied voice of a woman reading groups of five numbers -
"1-2-0-3-6" - in a clipped, upper-class English accent.

To get to grips with what was going on, it helps to go back to the
1920s. The All-Russian Co-operative Society (Arcos) was an important
trade body, responsible for overseeing transactions between the UK and
the early Soviet Union. Or at least, that's what they said they did.

In May 1927, years after a British secret agent caught an employee
sneaking into a communist news office in London, police officers stormed
the Arcos building. The basement had been rigged with anti-intruder
devices and they discovered a secret room with no door handle, in which
workers were hurriedly burning documents.

It may have been dramatic, but the British didn't discover anything that
they didn't already know. Instead the raid was a wake-up call to the
Soviets, who discovered that MI5 had been listening in on them for years.

"This was a blunder of the very first order," says Anthony Glees, who
directs the Centre for Security and Intelligence Studies at the
University of Buckingham. To justify the raid, the prime minister had
even read out some of the deciphered telegrams in the House of Commons.

The upshot was that the Russians completely reinvented the way messages
are encrypted. Almost overnight, they switched to "one-time pads". In
this system, a random key is generated by the person sending the message
and shared only with the person receiving it. As long as the key really
is perfectly random, the code cannot be cracked. There was no longer any
need to worry about who could hear their messages.

Enter the "numbers stations" - radio stations that broadcast coded
messages to spies all over the world. Soon even the British were doing
it: if you can't beat them, join 'em, as they say. It's quite difficult
to generate a completely random number because a system for doing so
will, by its very nature, be predictable - exactly what you're trying to
avoid. Instead officers in London found an ingenious solution.
They'd hang a microphone out of the window on Oxford Street and record
the traffic. "There might be a bus beeping at the same time as a
policeman shouting. The sound is unique, it will never happen again,"
says Stupples. Then they'd convert this into a random code.

Of course, that didn't stop people trying to break them. During World
War Two, the British realised that they could, in fact, decipher the
messages - but they'd have to get their hands on the one-time pad that
was used to encrypt them. "We discovered that the Russians used the
out-of-date sheets of one-time pads as substitute toilet paper in
Russian army hospitals in East Germany," says Glees. Needless to say,
British intelligence officers soon found themselves rifling through the
contents of Soviet latrines.

The new channel of communication was so useful, it didn't take long
before the numbers stations had popped up all over the world. There was
the colourfully named "Nancy Adam Susan", "Russian Counting Man" and
"Cherry Ripe" - the Lincolnshire Poacher's sister station, which also
contained bars of an English folk song. In name at least, the Buzzer
fits right in.

It also fits with a series of arrests across the United States back in
2010. The FBI announced that it had broken up a "long term, deep cover"
network of Russian agents, who were said to have received their
instructions via coded messages on shortwave radio - specifically 7887 kHz.

Now North Korea are getting in on the act, too. On 14 April 2017, the
broadcaster at Radio Pyongyang began: "I'm giving review works in
elementary information technology lessons of the remote education
university for No 27 expedition agents." This ill-concealed military
message was followed by a series of page numbers - No 69 on page 823,
page 957 - which look a lot like code.
It may come as a surprise that numbers stations are still in use - but
they hold one major advantage. Though it's possible to guess who is
broadcasting, anyone can listen to the messages - so you don't know who
they are being sent to. Mobile phones and the internet may be quicker,
but open a text or email from a known intelligence agency and you could
be rumbled.

It's a compelling idea: the Buzzer has been hiding in plain sight,
instructing a network of illicit Russian spies all over the world.
There's just one problem. The Buzzer never broadcasts any numbered messages.

This doesn't strictly matter, since one-time pads can be used to
translate anything - from code words to garbled speech. "If this phone
call was encrypted you'd hear "...enejekdhejenw...' but then it would
come out the other side sounding like normal speech," says Stupples. But
this would leave traces in the signal.
To send information over the radio, essentially all you're doing is
varying the height or spacing of the waves being transmitted. For
example, two low waves in a row means x, or three waves closer together
means y. When a signal is carrying information, instead of neat, evenly
spaced waves like ripples on the ocean, you're left with a wave like the
jagged silhouette of an ECG.

This isn't the Buzzer. Instead, many believe that the station is a
hybrid of two things. The constant drone is just a marker, saying "this
frequency is mine, this frequency is mine..." to stop people from using it.

It only becomes a numbers station in moments of crisis, such as if
Russia were invaded. Then it would function as a way to instruct their
worldwide spy network and military forces on standby in remote areas.
After all, this is a country around 70 times the size of the UK.

It seems they're already been practicing. "In 2013 they issued a special
message, 'COMMAND 135 ISSUED' that was said to be test message for full
combat readiness," says Maris Goldmanis, a radio enthusiast who listens
to the station from his home in the Baltic states.

The mystery of the Russian radio may have been solved. But if its fans
are right, let's just hope that drone never stops.
